A church congregation has 149 members, and each member donates 10% of their income to the church. If the church collected 335250 dollars last year from its members, what would be the mean contribution of its members? What about the mean income of its members?
Please help, I'm so lost on what to do.

$335,250 / 149 = mean contribution
Let x = the income of all its members.
.1x = 335,350
x = total income of all members
x/149 = mean income of the members
